目的 动态观察乳腺癌患者辅助内分泌治疗5年后的血脂及肝功能水平的变化,探求辅助内分泌治疗与高脂血症及脂肪肝发病率的关系。方法 56例乳腺癌患者实行辅助内分泌治疗,术后随访5年动态抽血测定其总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL)、高密度脂蛋白胆固醇(HDL)及谷草转氨酶(AST)、谷丙转氨酶(ALT)、直接胆红素(DBIL)、总胆红素(TBIL)等参数的变化,B超监测其肝脏变化。结果 经过2年内分泌治疗TG由(1.203±0.723)mmol/L上升至(1.701±1.271)mmol/L,5年内分泌治疗后TG降至(1.389±0.706)mmol/L。经过2年内分泌治疗LDL由(2.497±0.990)mmol/L上升至(2.950±0.984)mmol/L,5年内分泌治疗后LDL为(2.867±0.886)mmol/L。结论 辅助内分泌治疗2年会导致其TG和LDL的升高,5年随访仅发现LDL升高,辅助内分泌治疗会增加乳腺癌患者诱发心血管疾病的风险。

Objective To explore the effects of continuous nursing intervention on the quality of life for breast cancer patients after breast conserving therapy. Methods 117 cases of patients with breast cancer were randomly divided into observation group(59 cases) and control group(58 cases). The control group were cared by routine postoperative care, including health education. On the basis of the control group, the observation group were cared by continuous nursing intervention, including cognitive intervention, psychological intervention, social support, life care, functional exercise, the prevention of complications and discharge instruction. The quality of life, anxiety situation, depression amd upper limb edema were compared in the two groups. Results There has no significant difference on the quality of life after 1 week in the two groups(P＞0.05); The quality of life after 1 month, 3 months, 6 months, 1 year for the observation group were higher than the control group(P＜0.05). There has no significant difference on the anxiety situation after 1 week in the two groups(P＞0.05); The anxiety situation after 1 month, 3 months, 6 months, 1 year for the observation group were higher than the control group(P＜0.05). The depression situation after 1 week, 1 month, 3 months, 6 months, 1 year for the observation group were higher than the control group(P＜0.05). The upper limb edema situation for the observation group were better than the control group(P＜0.05). Conclusion The effects of continuous nursing intervention on the quality of life for breast cancer patients after breast conserving therapy is good. It can improve the quality of life, situations of anxiety, depression and upper limb edema. It is worthy of clinical promotion.

目的 分析乳腺癌细胞中Snail与MTDH基因的作用,明确Snail是否通过结合于MTDH的启动子区域促进乳腺癌转移。方法 克隆、转染Snail基因至乳腺癌细胞,观察过表达Snail的乳腺癌细胞中MTDHmRNA及蛋白表达的变化;再使用免疫共沉淀法检测Snail与MTDH基因的共作用。结果 转染Snail基因进入乳腺癌MDA-MB-435细胞后,转染组、空白组和对照组中MTDHmRNA的表达水平分别为1.61±0.22、1.02±0.18、0.99±0.20,转染组高于空白组和对照组,差异有统计学意义(P<0.05),而后两组表达无差异(P>0.05);Westren blot检测结果显示,Snail可促进MTDH蛋白的表达;免疫共沉淀显示,Snail与MTDH在细胞内存在相互结合作用。结论 Snail在乳腺癌细胞中可通过结合于MTDH基因的启动子区域,促进MTDHmRNA转录及相关蛋白的表达,从而导致乳腺癌转移。

Objective To investigate the function of Snail to MTDH gene in breast cancer cells. Methods We observed the changement of MTDHmRNA and protein expression in breast cancer cell line MDA-MB-435 after transfected with Snail gene. Then, we used co-immunoprecipitation to determine the domain of Snail and MTDH binding in vitro. Results After transfected with Snail gene into MDA-MB-435 cell, the expression levels of MTDHmRNA in transfection group, blank group and control group were 1.61±0.22,1.02±0.18,0.99±0.20. The level of transfection group was significantly higher than the other groups(P< 0.05). Western blot showed that the expression of MTDH protein can be promoted by Snail. Co-immunoprecipitation showed that Snail and MTDH are binding interactions in breast cancer cell line MDA-MB-43. Conclusion Snail can promote transcription and expression of MTDH in breast cancer cells by binding to the promoter region of the MTDH gene resulting in metastasis of breast cancer.
